Testing the Efficiency of Solar Cells at Different Ambient Temperatures
Ivan Temelkovski

Abstract
Solar panels, known as popular sources of energy, have grown and developed significantly from day to day. Although they don’t use energy produced from classical (fossil) energy sources, these systems have a huge potential to overcome even the biggest energy problems and therefore they are subjected to this research. However, in order to produce enough energy to meet consumer demands, it is necessary to achieve rational use. In this regard, this paper examines the effects of ambient temperature on the efficiency of the photovoltaic conversion process, whereby the obtain results contribute to make a real estimate that will enable the most rational production of electricity. The goal of this paper is to examine the temperature characteristics of commercial samples of photovoltaic cells whose application is decorative night lighting. In addition to experimental realization, the analysis of the process is supported by LabVIEW-simulation.
